ELECTRO-MAVGNETIC TRANSMITTER.

.BPIICIPIC'ATION forming part Of Letters Patent N0.3 42.666, dated May 25, 1866.

I Application filed April 16, I865. Serial No. 162,486. (No model.)

I tors; of which the following is a specification.

.This inventionrelates to electromagnetic conveyances or transmitters; and it consists in lo the novel combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, illustrating my invention, in which- Fig'hre 1 represents a sectional side view.

I I Fig. 2 is a transverse section in the plane xx, 1. Fig. 1. Fig. 3 is an inverted plan of one of the helices on a larger scale than the previous "figures, Fig. 4 is a longitudinal section when the core extends tii'roug'li"inoi-e thnn'two hel- Fig. 5 is a diagram showing the connections Fig. 1, the several helices being placed in a position parallel to each other, instead of their true position inline with each other, in

order to be able to show said connections.-

2 5 Fig. 6 is a sectional view of a modification of the means for introducing the helices successively into an electric circuit. Fig. 7 is an elevation showing the guide through the hel ices on which the core or carriage tmvels, 3 made in the form of a trongluand which may be made of any desired cross-section. Fig. 8 isa-transverse section of Fig. 7 Fig. .lshows the guide made in the form of a skeleton track and which may consist of two or more rails. Fig. 10 is a transverse section of Fig. 9.

Similar letters indicate corresponding parts. In the drawings, the letter A designates a tube of brass or any other suitable non-magnetic substance. Upon this tube are mounted 4 at stated intervals, a greater or less-distance from one another, a series of helices, B B B". B,wound upon spools of wood, or other-nonconductor of electricity.

The arrangement of the helices apart from each other enables me to construct myapparatus in curved as well as straight lines. My

arrangement also lessens the cost of construction, as less wire is required than when the helices are in juxtaposition, and by lessening 5 the number of contact-points, which Iaceomplish by thus arranging the helices apart from each other the expense of maintaining the apparatus is reduced. It furthermore allows the carriage to move freely in its track without material resistance from the air, as the air 5 5 is free to pass out between the helices.

In the example shown in FigsJ, 2, audit the tube A is made of brass, having one end ot the wire from each helix brazed or soldered or otherwise nictallicall y connected thereto, while the other end of each helix is connected respectively to a contact-piece, I) I), which has a contact-point, a, of platinum attached thereto. (Best seen in Figs. 2 and 3.) Through the flanges of the spools containing the helices ll 13' 13* B extends an electric :comluctor, E, which isinsulated from the tube A and from the helices, and on this conduct-or are mounted a series of magnets, F F F F, which, in the example shown in Figs. 1, 2, and 3, iiavctheform oi hursesho'es, null-which embrace the helices B 13 B B respectively. These magnets are so constructed that they can swing a limitcdfldistance upon the eondoctor in a plane at right angles to the axis 01 the tube A.

G is .the body or carriage, which fits the tube A, and to which motion is to be imparted. In the example shown in the drawings this carriage is made in the form of a perl'nanent mag- 8o not; or a carriage of soft iron may be used, as hereinafterdescribed. The opposite poles of this magnetic carriage are marked N and Sin Fig. 1. while the opposite poles of themagnets F F F F are marked a and s. (See Figs. 2 and 8 5 3.) The tube A connects by a wire, 10, with one pole of a generator of electricity--lor example, a dynamo-electric machine, Haud the-conductor E connects by a wine, 11, with the opposite pole of said dynamo-machine. carriage G is iutroduced into the tube A in the direction of arrow .1 the north pole not magnet 'Fis attracted by the south pole S of said carriage as soon as the same comes approximately opposite to the magnet, and it is brought :1 contact with the platinum point of the contactpicce I). A. circuitis closed through wire 11, conductor E, magnet F,.contact-picce Ll), helix 3, tube A, and wire 10 back to the dynamo-machine. The helix B is vitalizcd, and by the 1. axial magnetism the carriage G is moved forwardin the tube A. As soouas the south pole S comes opposite to the northpolc 'n of the magnet F,.the helixB is vitalizcd, and a .fresh in;-

SEARCH RC \Vhen the 0' iii pulse is imparted to the carriage, and so on by every helix through which the carriage passes. At the same time, whenever the center or new tral point of the carriage passes the north pole of one of the magnets F F F F the contact previously made between said magnet and the corresponding helix is broken, and the vitalization of this helix stops.

In order to impart to the carriage a continu- I0 ons motion through the tube A, it is necessary that the length of the carriage and the distance between the several helices shall be so proportioned that the successive helices are vitali zed in time to keep up the motion of the carriage; or, in other words, the length of the carriage must at least be equal to the distance between the magnets F F of the helices B B in order to insure its start. After starting, the helices may be farther apart; but I prefer the proportions above mentioned, in order that there may be no dead or neutral point in the apparatus; or, in other words, the carriage should be of at least such length that, should the circuit become broken through accident or otherwise, and the core or carriage come to rest, it cannot come to rest atany point but that, when the circuit is again'eompleted, it will be in position to be acted upon by the helices, and will resume its movement. If desired, the carriage can be made of any desired greater length. r In Figs. 4 and 5 I have substituted for the horseshoemugnets F F F" F the steel-bar magnets F F F" F F F" F". \Vhen' the carriage is introduced at B, the magnet F is attracted against contact n, Fig. 5, and a circult is closed through wire 12, contact at". magnet F, wire 20, helix B, and wires 21 13 back to the dynamo-machine, the helix B is vitalized and causes the carriage to move in the direction of the arrow marked thereon in Fig. 4. When the carriage has reached the position shown in Fig. 4, the south poles of the magnets F and F are attracted against the contacts a and s, respectively, Fig. 5, while the north poles of the magnets F" and F areattracted agai nst their contacts 11'' and n ,respectively. Acircuitpassesfromthedynamomachine through wires 12 and 18, contact a", magnet F", wire 19, helices B B", wire 16, magnet F, contact 8, and wires 17 and 13 back to the dynamo-machine, and a small portion of the current also passes from the dynamo machine through wires 12 and 14 to contact 12',

thence through magnet F and wire 15 to the helices B B B, and through wire'16, magnet F, contact 8, wires 17 and 13 back to the dynamo-machine, and the carriage keeps moving iu'the direction of the arrow marked on it in Fig. 4. As the movement of the carriage proceeds, the magnets F F F" are success'ively changed until the carriage finally stops.

In this case the tube A can be dispensed with,

but the helices BB'BB B Bare vitalized and devitalized by'the action of the carriage, the

surge; as in the example shown in Figs. 1, 2, all s u I In Fig. 6 I have shown an example of my apparatus with a carriage of soft iron and with circuit-closers actuated by said carriage.

B B"Bare the helices, which are supported upon'the tube .A in the same manneras in the apparatus shown in Figs. 1, 2, and 3. The helices connect at one end by wires 22 23 24 with a wile, 2.1, which connects with one pole of the dynamo-machine, while the other ends 0? said helices connect with contact-pieccsj" f f. Close to these contact-pieces, but insn-' lnted from the same, are contact-pieces y gr" g, which connect by wires 26 27 28 with a wire, 29, leading to the second pole of the dynamomachine. In theinterior of the tube are springtappets h 11" h, one for each helix, and the free ends of these tappcts extend through tube A, and are situated opposite the contact-pieces f gf" f g, respectively. The carriage G is supposed to more in the direction of the arrow shown on it in Fig. (i. In the position which the carriage occupies in this figure a circuit is closed through wires 25 23, helix B", contacts f 2 9 (the tappet h being raised,) and wires 27 29, and as the carriage moves on, the tappct h is raised and the tappet h" is rclc ased, so that the helix B is vitalized while the nelix B becomesdevitalized. v

If the apparatus is to be used ih'r transporting purposes, the carriage mustbo made 1101' low and of a size suitable for the purpose for which it is designed, so as to be able to contain the articles to be transported; but when used for pushing any article or thing before it or for hauling them after it, it may be solid; or, if made hollow, may be closed, and it may be provided with suitable means for enabling one to attach to it such articles or bodies as are to be moved or propelled by it through or along the tube or track.

The tube A can be made circular or of any other desired cross-section, or a trough or a track may be substituted for the tube, the construction being such that the carriage will be safely guided and kepttherein while permitted to move along and through it.

What I claim as new, and desire to secure by Letters'Pateut, is-- 1. The combination, with a series ofthree or more helices placed at suitable distances apart, and with a tube, trough, or track extending through said helices, of a hollow core or carriage which can freely pass through said helices, and a series oi'circnit-closers, one for each helix, detached from said carriage and their connections with a dynamo-machine or other source of electricity, said circuit-closers being actuated by-thc passing carriage and serving to close and to brcalrthe circuits through the successive helices in the series, substantially as desc bed.

i The combination, substantially ashcrein shown and described, with a series of helices placed inline with each other, and with a mag netic core or carriage which can freely pass through all the helices, of a series of circuit closers actuated by the magnetic influence of SUBSTlTUTED FOR MiSSlNG COPY,
